All the parts illustrated in the present drawings are similar to those illustrated and described in said patent except the means for setting up the stop pins which control the rack bars, and the arrangement of. the forward tot-a1; izers. I shallnot, therefore, go into an extended explanation of the construction and operation of the entire machine, relying upon said patent and said application for a full description thereof.

The stop carriage is in the form of a rota table cylindrical magazine containing stop pins which are capable of being moved into cAncULA'rmG-Macnmn Specification of Letters Patent.

Application filed October 21; 11308.- Serial No. 458,823 I ar cam operative position by depressing-corresponding keys on thekey board of" the calculating machlne. The keys which coiiperate with the stop carriage elevate the stop pins and cause them to move into ali'nement with prototalizers. These stop pins travel in circular are operated, and after they have served as stops said stop pins are restored to their normal positionby passing under a stationplate. eferrmg to the accompanying drawings, bars a connected to the keys of group A (see Fig. 2) are mounted one-common pivot 21 and extend rearwardly under a plate 22 see Fig. 3) mounted in the free end a frame 23.

frame 23 to an arm 301 loosely mounted on a shaft 302 and provided with a pawl 303 which cooperates with a ratchet wheel 304, the latter being frigidly connected to disks 305.

The cylindrical magazine 57 (see Figs. 8 to 13) containing the'stop pins is preferably composed of ten wheels or disks 305 each provided with its complement of stop pins 62 which are preferably radially disposed, sald pins being also movable radially. Stop pins 62, however, may be tangentially arranged if desired. The stop pins are held means of ring plates 305 (see Fig. 11'), between which and the disk 305 are suitable slotted or perforated plates 305 (see Fig. 13) forming guides for the stop pins. Stop pins 62 coiiperate with springs 62" which frictionally hold them in their set and retracted positions. The pins 62 on the difierent disks are arranged in longitudinalalinement so asto form longitudinal series of pins for cooperatin 'with the stop shoulders 100" on the rack ars, arresting said rack bars in one of ten different positions depending upon the stop pin which is set.

56 are key-actuated rods or bars Fi s. 2 and 3) which extend up between the dis 's where their ends are bent laterally or formed with a lateral rojection56 so as to lie under the stop p1ns'62 com rising a longitudinal series. The 11 per ends of the bars 56 are preferably inc ined, as shown i in Fig. 11', and guided between the" teeth of jectio'ns on the rack bars'which operate the.

300 indicates a link which connects the- Patented Feb. 3,1914.

paths and advance step-by-step as the keys in position on their respective disks by two comb plates 307 and 308, which teeth extend into .the spaces between the stop-carrying disks. 4

All of the disks 305 are secured together by pins or rods 306, (see Fig. 12) said disks rotating together as a cylinder on the shaft 302. It is obvious'from the above description that the stop-pin-carrying cylinder com posed of the ten separated disks above described has circumferential grooves or spaces between the disks for the operating bars 56 and their guiding combs.

309 is a plate loosely mounted on shaft 302, which plate is provided with a pawl 310 (see l ig. 9), for cooperating with a ratchet wheel 311 conjoined to the cylindrical stop carrier 57.

100 indicate pawls carried by the rack bars 100, (see Fig. said pawls cooperating with a plate 300 and constituting releasing mechanism whereby the rack bars, beginning with the rack bar of lowest order, are successively released as the keys are successively operated in setting up an item in the traveling field of stops.

The operation of the above described parts is as follows: When the rear end of one of the bars a israised, frame 23, which is connected by link 300 to arm 301, is rocked upwardly and the pawl 303 on said arm moves the ratchet wheel 304 and carriage 57 in the direction indicated by the arrow in Fig. 8, thereby bringing the elevated stop pin 62 into alinement with the units rack bar, and at the same time the ratchet 311 which is rigidly secured to the rear end of carriage 57 moves the pawl 310 in the direction indicated by the arrow in Fig. 9, thereby moving the stop plate 309 out of aline-' ment with the pawl 100 on the units rack bar. It will be readily understood that if another key in group A is depressed, the stop pin just referred to will be moved into alinement with the tens rack bar, plate 309 will move out of alinemeut with said tens rack bar, and another stop pin will be raised and moved into alinement with the units rack bar. When all thestop pins 62 are raised in introducing an item into the machine,lthey are located in front of projections 100 on the rack bars 100, and the rack bars move forward they arearrested in one of nine different positions by said stop pins 62.

One of the forward totalizers or registers in operative relation to the racks, is now thrown into engagement with the racks when the racks are in their forward position, after which the restoring bar 104; picks up the rocking levers 102, which have slot and pin connections with the racks, (see Fig. 3) and restores the racks to their normal position, and by so doing introduces the item into the register wheels. The rocking levers 102 the same constituting the operating mechanism for the racks are connected to springs 103 which tend to pull them forward.

The means for preventing the overthrow of the stop cylinder consists of the upper end of the keypositioned bar 50. (See Fig. 11.) This being a ten-key machine, but one key at a time operated, and consequently but one bar 50 is raised. The depression of the key coincident with the elevation of the bar- 50 causes the stop cylinder to move forwardly the distance of one step, during which movement bar 56 is raising the stop pin 62. As the bar 50 reaches the limit of its upward movement and the stop pin (32 is positioned or'set, the stop cylinder has been rotated such distance-that the lower end of the stop pin immediately behind the upper end of bar 50 engages the rear face of said bar and prevents the cylinder from over-rotating. Should the key be struck forcibly so as to move the stop cylinder with an impulse tending to overthrow it, the up per end of bar 53 will be brought against the comb plate 307. The inclined upper end of bar 50 in engagement with the lower end of stop pin inn'nediately behind it, will,whcn the bar 50 descends, cause the stop cylinder to rotate reversely a slight distance to its proper position, which proper position is determined by the pawl 303 which, in this operation, acts as a centering pawl. The parts are so proportioned that the overthrow is not equal to or greater than the distance between the teeth on the ratchet 304. Thus, upon the operation of any digit key the stop cylinder will be advanced one step and no more.

The shaft 302, which supports the rotatable stop carriage, is mounted in a frame 312 pivoted at 313 to brackets 31 1 (see Fig. 8). In introducing an example into the machine, the operating handle (see Fig. 1), whichis pulled forward at each operation of the machine. through suitable connections. causes (unless the operator positions means to prevent it) the forward totalizer wheels to be thrown into mesh with the rack bars, so that upon the return movement of the handle the rack bars will introduce the item into the forward totalizer wheels. This movement of the forward totalizers into and out of engagement with the rack bars is, utilized to depress and lift the cylinder of stop pins in the following manner: Fixed on the shaft 81,- which shaft is operated at each stroke of the handle 65, is a rocking plate 109 provided with a, shoulder 110, "(see Fig. 0), which, when the plate is nearing the limit of its forward movement, conies in contact with a pin 111 carried by a tappet 112 mounted on a bar 113 normally held in a raised position by a spring 114:.

' 115 is a'plate fixed to the framing of the machine and against which the upper cam edge of the tappet 112 rests. When the shoulder 110 strikes the pin 111 the tappet is rocked on its fulcrum on the. bar 113 and thereby forces the bar 113' downwardly.

-VVhen the'plate 109 is nearing its home pothe shoulder 116, so as. to permit the depres:

sion of the bar 113 without interference from the plate 109, as, for instance, in the taking of a total.

After an example has been set up-in the machine, the forward movement of the operating handle will cause the rack bars to vmove forwardly under the impelling action of the springs 103 until arrested by the pins 62. Then the cam plate 105) causes one of the forward totalizers to be engaged with the rack bars and when the handle is moved rearwardly the bar 104 restores the rack bars and actuates the totalizer wheels. intro-;

ducing the item thereinto.

The bar 113 which moves the front totalizer wheels 119 into and out of engagement with the rack bars is provided with an extension 113 (see Figs. (3 and 7). which extension coi perates with a swinging frame 312 which carries the stop cylinder. andwhenever the bar 113 is depressed the frame 312 and its stop cylinder is likewise depressed, the depression of said stop cylinder causing'the stops which have not been restored to-be moved out of the paths of the shoulders 100 on the rack bar.

The pivoted frame 319 which carries the stopcylinder is provided with a. spring 315 (see Fig. 8). which lifts said frame and its carried stop cylinder into operative position when permitted to rise bythe projection 11?).

Thereleasing plate. 309 which is mounted on the stop cylinder and moved laterally step by step at each operation'of the item keys must be released and returned at each operation of the handle, and this is accom- I plished by providing a pawl 310 with a pin 316. which extends through a slot in the plate 309 (see Fig. 10), and rests upon a relatively stationarv curved track bar 317 (see Figs. 8 and 9). Thus, whenever the stop cylinder is depressed it'carries ith t 'the plate 309. which not only releases all of the rack bars so far as any restraint by said plate 309 is concerned. but the pawl 310 .is raised out-.of engagement with the ratchet 111. and a spring 318 connected to the plate 309 restores said plate 309 to its normal position, which normal position is determined by the comb plate 240%) (see Fig. 9). The

lifts the pawl 310 when the plate 309 is depressed.

As the stop plate 309 is disengaged from the pawl s 100 of the inoperative rack bars when it is moved down, these rack bars are.

temporarily restrained from moving forrelatively fixed bar 317 is the medium which ward by spring-actuated pawls 208 (see-Fig.

3). which pawls are normally held in the position shown by a rod 210'sec-ured to arm 211, but which engage the teeth of the rack bars when the restoring bar 104 is innits forward position. I have not shown in the drawings the connection between the restoring bar 104 and the pawls 208 as the same.-

7 In my present construction the cylinder.

of stop pms is advanced step-by-step as each pin is set up. and contemporaneously with the setting up of a stop pin the rack bars are successively released until the rack bars of the different denominations embraced .withinthe number are free. Vi hen the bandle is operated the active rack bars may move forward and be arrested by the stop pins in their paths, after which the totalizer is thrown into mesh with the rack bars, and

when the-rack bars are restored the totalizer wheels are rotated in proportion to the movement of. the rack bars. The plate 309 is likewise restored in front of the latchpawls on the rack bars in readiness for the When I the first number of the next example to be introduced into the machine is struck on the keys. the stop pin will be set and advanced in line with the units rack bar. At the same is advanced in front of the tens rack bar,-

hnt as the tens rack bar is locked against movement by the plate 309 it is obvious that such stop and all other stops to the left thereof in the cylinder which may stand.

se are ineffective ith respect to the rack bars of the machine which arelocked against n1ovement. Eventually these stops are restored by means of the cam plate 319 before they ag'ainenter the zone of the rack bars. I

115 time the units rack bar is released by the The register wheels 119 (see Fig. 3) are mounted in frames 122 pivoted at 320 and having extensions 321 which are adapted to be engaged by a rock frame 322 said rock frame being secured to a shaft 323 having an arm 82st (see Fig. (3) which is pivotally connected to the bar 113. The lower end of bar 113 carries a pin which cooperates-with a lever 325 connected tothe total. key bar. \Vhen bar 113 is moved down by the total kcy T, Fig. 2, the register wheels 11.9 are thrown into engagement with the rack bars, and the extension 113 on bar113 depresses the frame 2312, thereby moving the stop plate 309 out of alinement with all of the pawls 100", so that. the register wheels 119 are in engagement with the racl; bars and free to mote 'in the total-taking operation.

To obtain the total, the total key (marked T in Fig. 2) is depressed, which moves bar 113 downwardly and causes ,the register wheels in operative relation to the racks to engage with the racks before the racks start on their forward movement. and quently the register wheels, if not standing at zero, will be rcverse y rotated until. the. printing type :arried by the' forward end of the rack exhibit the total of the amount registered. A product register represented by the wheels 268 also cooperates with the racks 100, and if desired, instead of introducing an example into one of the groups of register wheels mounted on the reel, the D key'may be pressed and the example intro duced directly into the wheels 268, as fully set forth in the aforesaid patent.

To obtain the product or total indicated on the register wheels 268, the P key is depressed and the power shaft of the machine operated. In total-taking operations following the depression of the P key, the frame 12 is likewise depressed carrying with it the cylinder of stop pins and plate 309. thus permitting free movement of the racks as in the case of the total-taking operation when the T key is depressed.

The operation of multiplication is performed by setting up the multiplicand through the medium of the keys in group A. and pressing the R- key, which results in setting up the example. in the multiplying devices. The multiplicand, if already set up 2 in one of the forward totalizers, may be racks.

transferred through the medium of the racks 100 by pressing the E key and operating said The digits of the multiplier are separately set up by pressing the keys in group B. lVhen a. key in group B is de pressed the power shaft must be operated twice, except for the zero character, for the purpose of obtaining tens and units partial products which are introduced in the register wheels 268 and there added to form a complete product. 1 When a complete product is obtained the P key may be pressed and the product recorded. Suitable carry ing mechanism is provided for the wheels 268. (See Fig. 3.) After keys in group B are depressed and a number set up in the multiplying devices, the stepped extensions 243 are'raiscd by actuating the operating handle, and, by coiiperating with pins 242, said extensions 243 serve as stops for the rack bars 1.00. At the time the stepped extensions 243 are positioned to serve as stops, a bar 356 is raised and the stop pin carriage 57 and its stop plate 309 are lowered. Bar 35(5is connected by a link 5321} to a lever 327 and as the free end of lever 327 lies ahov a flange 309 on the step plate 309. the carriage 57 will be moved down when bar 356 is raised. The purpose of this is to prevent interference on the part of the plate 309 or any of the unrestored stops in thecylinder 57 from interfering with the rack bars 100 in the multiplying operations.

The means for depressing the stop cylinder whenv the product register wheels 2138 are brought into engagement with the rack bars 100 con'ipriscs an extension 272. on bar 272, which bar 272 is connected to the pivoted frame which carries the wheels 268. Ex tension 272 cooperates with the pivoted frame 312 which supports the stop cylinder (see Figs. 4, G and 7).

T he I2l(l( bars carry printing type 1 18 by which the items and the total thereof introduced into the adding register or totalizer may be recorded, and when a complete product is obtained said product maybe recorded. 4

The paper on which the printing record made cooperates with the platen X arranged in the carriage at the top of the machine, (see Figs. 1. and which carriage is movable across the machine. 'lypewriting mechanism is also used to print words and characters on the paper in the carriage in line with the type impressions derived from the type carried by the rack bars of the cal culating machine.

Referring to Fig. 3, it. will be seen that the. forward totalizcrs are three in number but it obvious that this number could be changed. The totalizer wheels 115.) are loosely mounted on their respective shafts, which shafts are carried by frames 122 pivotally connected at 320 to side plates .20 and provided with ex tensions 321 which are adapted to be on gaged by a rock frame 322. said roclt frame being secured to a shaft 323 having an arm 32 1 pivotally connected to bar 113. The totalizer shafts extend through slots in the side plates 120 and the wheels 11.) are normally held in the elevated position shown in Fig. 3 by means of springs 328 connected to the ends of said shafts. The side plates 120 are rigidly connected to a shaft 121. journaled in stationary bearings 329. It will be seen that the side plates 120 are arranged teeth on the bars 129.

to form three separate compartments, and that each compartment contains a set of totalizer wheels-and carrying mechanism therefor.

The carrying mechanism for the register wheels 1-19 is similar in operation to the carrying mechanism-"shown in the patent and application referred to with the following diiference: .In lieu of a single set of carrying devices common to "all the totalizers, there is a set of carrying devices for each totalizen. One of these will now be described. The carrying teeth which engage the re i'ster. wheels are arranged on. a horizontal' y movable bar 129 which is restrained from movement by a pawl 124:. Thispawl is controlled-by a pendant 121 operated by tripping projections 119 (shown in Fig. 4) on the register wheels 119. \Vhenever one of the pendants 121 is operated to release the pawl 121, the bar 129 jumps forwardly to a position where the pawls 124 will not enter their notches. At this time the register wheels 119 are in mesh with the racks 100,-'and, of'course, out of mesh with the lVhcn the register wheels 1l9fare disengaged from the racks 100 and thrown into mesh with the teeth on bars12-9, a'restoringplate 137 which occu pied the position shown in dot and dash lines in Fig. 3, and held the bars 129 against movement, is vibrated to release the bars 129 and effect the carrying.

The plate 137 is operated bya linlt 138' having a tappetwhich cooperates with the cam plate 82 (see Fig. 6). The operation of this cam plate'82 is such that when the handle moves forward the tappet is idly vibrated, leaving the restoring plate away .from the bars 129. As the handle moves rearwardly the tappet and bar 138 are lifted so as to move the restoring bar inwardly, restoring all of the bars 129, the heel of the I cam face at the rear end of plate 82 insuring the proper seating ofthe pawls 124 by imparting to the-bars a slight excess movement. The restoring plate then drops away from the bars 129, a slight distance, so that .if any of the pawls l24are-tripped when the adding wheels are being-rotated they will release the bars 1 29, but said bars will be restrained from movement until the tappet drops into the-recessat the forward edgeof the cam plate. At this time the handle has disengaged the adding wheels from the racks, said adding wheels in such movement becoming engaged with the bars 129. Aftersuch engagement the restoringplate is moved away from the bars 199V and carrying is effected; Thus, at the-end of each operation the adding wheels stand fully carried when the handle is in its home position, but the-bars 129 are not restored until the handle starts on its rearward movement upon thesucceeding operation thereof.

- The carrying mechanism of the rear totalizer cooperates with a restoring plate 137" which is actuated by bar 138 and the wheels of this totalizer are mc"ed into and out of mesh with t-he'rack bars by means of a bar 272.

To revolve the totalizers and bring them successively into mesh with their actuating racks, I arrange a spring drum 140 on the end of shaft 1:21, which spring drum tends at all times to rotate the shaft 121 in one direction. To rotate shaft 121 in the opposite direction I arrange a cable 141 on said spring drum, said cable being connected to a bar 1 12 having escapementteeth 1&3 (see. Figs. 3, 4 and 5). 14% is a pivoted rocking plate which cooperates with the'escapement.

spring in drum 140 to revolve the totalizers and present the appropriatetotalizer in operative relation to the actuating racks for each separate column. The left hand end of esca-pement bar 1. a! CO6PGPILQS with the fixed stop 143 on the paper carriage, whereby whenever the paper carriage is moved from left to right the totalizers are revolved to their normal or starting positions. In

Fig. the totalizers have been marked 1, 2 L

and 3, and if we assume that the machine is normal when totalizer 1 is in operative relation to the racks it isobvio'us that after the paper carriage is moved toward the left, so that numbers maybe printed in the sec- 0nd column, the first tappet 145 will operate the escapement mechanism and bring totalizer number 2 in operative relation to the racks. The steps in the partial revolutions of the totalizcrs continue until totalizer number is brought in position to register the number recorded in the third column. When the carriage is restored to its normal position at the right the totalizers will be revolved so as to bring totalizer number 1 in operative position to the actuating racks. A In the event that an error occurs in the introduction of an example in the machine, an error key 206 (see Fig. 2) may be operated to reset the multiplying devices, as in the patent and application before mentioned, and if desired a connection can be made between said error key and the pivoted frame 312, whereby Whellifltlid error key is operated said-,.fram'e'- wiillbe'depresse'd so as lift the pawl 310 and release the plate 309, permit-ting said plate to be restored to its normal position.

While Ihave illustrated in this application means for depressing the stop cylinder for the purpose of preventing interference with the movement of the rack bars by the stop pins and plate 809, it is obvious that other means could be provided for permitting the racks to move without interruption from the stop pins or the plate 309. For instance, instead of depressing the stop cylinder and plate 309 means could be provided for advancing the stop cylinder the distance of one-half a step so that the stop pins would be located between the bars and thus permit free movement of the bars. The means which advanced the cylinder one-hall a step could depress the plate 809 independently of the stop cylinder. Or, means could beprovided for rotating the stop cylinder a distance equal to nine steps so that all the positioned stop pins could be moved out'of the path of the racks. \Vhen imparting such a movement to the stop cylinder the plate 309 could also be moved out of the path of the racks, and in this manner release the racks.

Having thus described the invention, what is claimed as new and desired to be secured by Letters Patent is:
